Question about Heating & Cooling
Coleman heater model # 7975A856 serial # 038972806
If your thermocouple is literally burning out, then have the pilot assembly checked and clean, check the orifice and the gas pressure to the pilot. Make sure the orifice size is correct for what type of fuel you are using (liquid propane or natural gas). Worst case you could have a gas valve or regulator going bad. Please have this done by a qualified service technician. I hope this helps.
